The 2019 Coronavirus Disease (COVID-19) has become an unprecedented public crisis. We retrospectively investigated the clinical data of 197 COVID-19 patients and identified 88 patients as disease aggravation cases. Compared with patients without disease aggravation, the aggravation cases had more comorbidities, including hypertension (25.9%) and diabetes (20.8%), and presented with dyspnoea (23.4%), neutrophilia (31.5%), and lymphocytopenia (46.7%). These patients were more prone to develop organ damage in liver, kidney, and heart (P < 0.05). A multivariable regression analysis showed that adv

Objectives . To evaluate the safety of moxa smoke, especially to provide quantitative information and details for the occupational prevention of acupuncturists. Methods . We combined the questionnaire-based cross-sectional survey and lung function testing-based historical retrospective cohort research to investigate the safety of moxa smoke exposure (MSE) among acupuncturists. A mathematical regression model was established to quantitatively evaluate the relationship between moxa smoke exposure and the respiratory health of the acupuncturist. The smoke exposure time of the acupuncturist and th

Background: Chronotype is the pattern of the circadian rhythm that allows an individual to optimize times of sleep and activity. It has been observed that chronotypes may associate with some conditions and diseases, including obesity. It is not known, however, whether chronotypes determine the effectiveness of weight loss regimens. Therefore, in the present study, we compared the outcomes of a 3-week moderate calorie restriction undertaken by individuals with obesity under the same controlled hospital conditions. Methods: A total of 131 participants with obesity (median BMI 40.0) were studied.

Cardiovascular toxicity is the most common cause of fatality in the first 24 hours of poisoning with aluminium phosphide (AlP). Most often manifesting itself in cardiac dysrhythmias. The aim of this study was to evaluate the benefits of amiodarone prophylaxis against cardiac dysrhythmia in 46 patients with acute AlP poisoning. They were divided in two groups of 23: one receiving amiodarone and the other not (control). The treatment group received amiodarone prophylaxis in the initial intravenous bolus dose of 150 mg, followed by a drip of 1 mg/min for six hours and then of 0.5 mg/min for eight

OBJECTIVE: To estimate the proportion of individuals with focal epilepsy treated with at least one among carbamazepine (CBZ), oxcarbazepine (OXC), or eslicarbazepine (ESL), who were hospitalized due to hyponatremia-related symptoms in 2024, and to test the hypothesis that there is an association with climatic variables. METHODS: We undertook a prospective study in which people with focal epilepsy treated with at least one of the target drugs and at least one attendance in 2024 formed the study cohort.

BACKGROUND & AIMS: Both liver stiffness measurement (LSM) and biochemical response have prognostic significance in patients with primary biliary cholangitis (PBC). However, the frequency and clinical relevance of discordant biochemical and LSM changes remain unclear. We aim to determine the performance of the most recent or current LSM (LSMc) in predicting first hepatic decompensation (HD) in the setting of discordant biochemical and LSM responses. METHODS: In this international, multicenter study, we included patients with at least two reliable LSM performed at least 6 months apart. Patients

Background: Neurodegenerative diseases, including Alzheimer’s disease and Parkinson’s disease, are among the leading causes of disability and mortality worldwide. Dietary patterns have emerged as modifiable risk factors that may influence disease onset and progression. The Mediterranean diet (MedDiet), rich in fruits, vegetables, whole grains, legumes, fish, and extra virgin olive oil, has been consistently associated with better cognitive outcomes and reduced risk of neurodegeneration.

Abstract Co-pathology is frequent in Lewy body disease, which includes clinical diagnoses of both Parkinson’s disease and dementia with Lewy bodies. Measuring concomitant pathology in vivo can improve clinical and research diagnoses and prediction of cognitive trajectories. Tau PET imaging may serve a dual role in Lewy body disease by measuring cortical tau aggregation as well as assessing dopaminergic loss attributed to binding to neuromelanin within substantia nigra. We sought to characterize 18F-PI-2620, a next generation PET tracer, in individuals with Lewy body disease. We recruited 141 p

The increasing incidence of Type 1 diabetes has coincided with the emergence of the low-fiber, high-gluten Western diet and other environmental factors linked to dysbiosis. Since Lactiplantibacillus plantarum 299 v (Lp299v) supplementation improves gut barrier function and reduces systemic inflammation, we studied its effects in spontaneously diabetic DRlyp/lyp rats provided a normal cereal diet (ND) or a gluten-free hydrolyzed casein diet (HCD). All rats provided ND developed diabetes (62.5±7.7 days); combining ND with Lp299v did not improve survival. Diabetes was delayed by HCD (72.2±9.4 day

Abstract Epstein–Barr virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer and neurological disorders. Although primary infection is often subclinical, persistent EBV infection can drive immune dysregulation and long-term complications. Despite the ubiquity of infection, the determinants of EBV persistence following primary exposure remain poorly understood, although human genetic variation partially contributes to this phenotypic spectrum 1–3 . Here we demonstrate that existing whole genome sequencing (WGS) data of human populations can be used to quantify persistent EBV D

The migration-proliferation dichotomy (MPD) has long been observed in cultured cancer cells. This phenomenon is not only relevant to tumour progression but may also have therapeutic significance in clinical cancer. However, MPD has rarely been investigated in primary cancer. This study aimed to either confirm or disprove the existence of MPD in primary cancer. Using primary gastric, colorectal and prostate cancer (GC, CRC and PCa) cohorts from the Cancer Genome Atlas and Memorial Sloan Kettering Cancer Center, this study interrogated the MPD phenomenon by utilising RNA-Seq-based proliferation

Short-chain fatty acids (SCFAs) are metabolites derived from the fermentation of dietary fibre by gut bacteria. SCFAs function as essential regulators of host-microbiome interactions by participating in numerous physiological and pathological processes within the gastrointestinal (GI) tract. In recent years, the depletion of SCFAs has been increasingly linked to the pathogenesis of GI diseases. In this review, we summarize the current understanding of the therapeutic mechanisms of SCFAs in GI diseases, including inflammatory bowel disease, irritable bowel syndrome, metabolic dysfunction-associ
